OPTIONAL RELAYS
CR3-12 - SENVA N.O. 12 VDC Command Relay
Command Relay for all 23XX Series, N.O. 10A @ 125VAC, 9-12VDC 30mA nom
The current status sensors can be used for monitoring fan or pump proof of flow. The switch set point is self-calibrating to normal and an alarm will go off upon loss of load. The sensor will compensate dynamically to moderate load changes to prevent false trips and automatically calibrate for load variances caused by air balancing. Contact closure will be made any time the motor is operating above the setpoint. The sensor will provide visual indication in the form of LEDs for output status and sensor power. Scaled for manual calibration to detect belt loss eliminating the need to go back to the job.List:
